  • Field Details

    • EVENT_TOPIC

      static final String EVENT_TOPIC
      Service registration property (named event.topics) specifying the Event topics of interest to a Event Handler service.

      Event handlers SHOULD be registered with this property. The value of the property is a string or an array of strings that describe the topics in which the handler is interested. An asterisk ('*') may be used as a trailing wildcard. Event Handlers which do not have a value for this property must not receive events. More precisely, the value of each string must conform to the following grammar: 

       topic-description := '*' | topic ( '/*' )?
 topic := token ( '/' token )*

    • EVENT_FILTER

      static final String EVENT_FILTER
      Service Registration property (named event.filter) specifying a filter to further select Event s of interest to a Event Handler service.

      Event handlers MAY be registered with this property. The value of this property is a string containing an LDAP-style filter specification. Any of the event's properties may be used in the filter expression. Each event handler is notified for any event which belongs to the topics in which the handler has expressed an interest. If the event handler is also registered with this service property, then the properties of the event must also match the filter for the event to be delivered to the event handler.

      If the filter syntax is invalid, then the Event Handler must be ignored and a warning should be logged.
